Quick Reference (2)

Resource type Mathematical Symbols and Abbreviations
This leaflet provides information on symbols and notation commonly used in mathematics. It shows the meaning of a symbol and, where necessary, an example and an indication of how the symbol would be said. For further information from mathcentre resources, a search phrase is given. This Quick Reference leaflet is contributed to the mathcentre Community Project by Janette Matthews and reviewed by Tony Croft, University of Loughborough.

This leaflet revises the meaning of the term 'percentage', and shows how to calculate percentages, and how to convert expressions involving percentages into alternative forms.

Teach Yourself (9)

Resource type Arithmetic and Geometric Progressions
This unit introduces sequences and series, and gives some simple examples of each. It also explores particular types of sequence known as arithmetic progressions (APs) and geometric progressions (GPs), and the corresponding series.
Resource type Decimals
In this unit we shall look at the meaning of decimals, and how they are related to fractions. We shall then look at rounding to given numbers of decimal places or significant figures. Finally we shall take a brief look at irrational numbers.
Resource type Fractions - adding and subtracting
In this unit we shall see how to add and subtract fractions. We shall also see how to add and subtract mixed fractions by turning them into improper fractions.
Resource type Fractions - basic ideas
What are fractions? Fractions are ways of writing parts of whole numbers. For example if we take a pizza, and divide it up equally between 4 people, each person will have 1/4 or, written in words, one quarter of the pizza.
Resource type Fractions - multiplying and dividing
In this unit we shall see how to multiply fractions. We shall also see how to divide fractions by turning the second fraction upside down.
Resource type Percentages
In this unit we shall look at the meaning of percentages and carry out calculations involving percentages. We will also look at the use of the percentage button on calculators.
Resource type Ratios
A ratio is a way of comparing two or more similar quantities, by writing two or more numbers separated by colons. The numbers should be whole numbers, and should not include units.
Resource type Rules of arithmetic
Evaluating expressions involving numbers is one of the basic tasks in arithmetic. But if an expression is complicated then it may not be clear which part of it should be evaluated first, and so some rules must be established. There are also rules for calculating with negative numbers.
Resource type Sigma notation
Sigma notation is a method used to write out a long sum in a concise way. In this unit we look at ways of using sigma notation, and establish some useful rules.
